GreenThumb - I am in a fully enclosed set-up using CO2 and rives is correct. It will not double your yield. When applied correctly with reasonable temp, humidity and nutrient parameters, it will allow for maximum growth rate and if you had all of those dialed and then added CO2, a yield increase should be seen. However, as I found out recently, everything else has to be dialed.
For example, I was on track for a great cycle, but had an unfortunate moment that put my girls in 121F for about 30-45min. Lost some tops and deffinetly slowed them down. Recovered now and on track, but all the CO2 in the world won't fix that moment.
Please also note, that there is a lot of "old mythology" regarding CO2 and running higher temps and really high PPM of CO2 as the way to go. I would suggest looking for Spurr's good write ups on why a dialed in +80f lights on and +70F lights off and right around 1000ppm is very reasonable.
At any rate, don't get too excited and go nuts with the set-up....... Make sure you test and dial in everything and that may take some time.
Best of luck to you! Azeo
I've been working on my cab for over a year now, so I have all the electronics and environmental control systems down.
I had a mistake like your temperature one happen a while back. Almost started a fire. Since then added in components and a few lines of code to stop that from happening again.
Thanks for the CO2 info, I'll search for Spurr's write ups.
How did you like using the retro white bulb? I really wanted to and completely set out to use the 315w elite 942 bulb but couldn't find a digital ballast for it and just couldn't see myself paying the $500 for the GEL kit. I even spent days hunting down end-user suppliers of the PGZ sockets and bought one... bah!
